Question

大家好，我正在尝试在我的表单上使用验证，我在样本中做了所有的事情并用Google搜索了很多次以找到解决方案但不幸的是我无法解决我的问题。

我的问题是：当我点击提交按钮时显示为空，它向数据库注册空，验证不起作用!!!!!!!!!!!!

我正在使用struts2 tomcat7 jdk7 spring4 hibernate3和sitemesh 2.4.2

任何人都可以帮助我

这是我的实体

    @GeneratedValue(strategy = GenerationType.TABLE, generator = "ct_key")  
    long id;  
    String bankName;  

    public BankInfo() {  
    }  

    public BankInfo(String bankName) {  
        this.bankName = bankName;  


    public long getId() {  
        return id;  
    }  

    public void setId(long id) {  
        this.id = id;  
    }  

    public String getBankName() {  
        return bankName;  
    }  

    public void setBankName(String bankName) {  
        this.bankName = bankName;  
    }  

    public String toString(){  
        return bankName  ;

}

另一件事是BankInfoAction-validation.xml和BankInfoAction.java在同一目录中

Answer 1

你应该使用

<field name="bankName">  
    <field-validator type="requiredstring">  
        <message key="errors.required"/>  
    </field-validator>  
</field>

因为此字段已填充。 modelDriven拦截器将模型放在值堆栈的顶部。所以，你不应该担心设置值。

Answer 2

3天后，我终于可以在老师的帮助下解决问题：我看到了所有配置验证，但是：第一个问题是：在提交＆gt;＆gt;之后，validatoin无法正常工作我的struts版本是struts2-core-2.3.14.3.jar我将它更改为struts2-core-2.3.15.x.jar并且它有效：）

第二个问题是：在提交验证消息后没有显示＆gt;＆gt;＆gt; 1天后，我找到了解决方案＆gt;＆gt;＆gt;＆gt;＆gt;问题是在我的textfields中theme =“simple”我把它改成了theme =“css_xhtml”

Struts 2 XML验证不起作用
